Disclosure Text Block [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	1	Organization and Description of Business
	Organization and Nature of Operations
	YuMe, Inc. (the "Company") was incorporated in Delaware on December 16, 2004. The Company, including its wholly-owned subsidiaries, is a leading independent provider of digital video brand advertising solutions. The Company's proprietary technologies serve the specific needs of brand advertisers and enable them to find and target large, brand-receptive audiences across a wide range of Internet connected devices and digital media properties. The Company's software is used by global digital media properties to monetize professionally-produced content and applications. The Company facilitates digital video advertising by dynamically matching relevant audiences available through its digital media property partners with appropriate advertising campaigns from its advertising customers.
	The Company helps its advertising customers overcome the complexities of delivering digital video advertising campaigns in a highly fragmented environment where dispersed audiences use a growing variety of Internet-connected devices to access thousands of online and mobile websites and applications. The Company delivers video advertising impressions across personal computers, smartphones, tablets, set-top boxes, game consoles, Internet-connected TVs and other devices. The Company's video ads run when users choose to view video content on their devices. On each video advertising impression, the Company collects dozens of data elements that it uses for its advanced audience modeling algorithms that continuously improve brand-targeting effectiveness.
	Basis of Presentation
	The Company’s consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”).
	In July 2013, the Company's board of directors and stockholders approved an amendment to the amended and restated certificate of incorporation. The amendment provided for a 1-for-6 reverse stock split of the outstanding common stock, effective July 24, 2013. Accordingly, (i) every six shares of common stock were combined into one share of common stock, (ii) the number of shares of common stock into which each outstanding option or warrant to purchase common stock is exercisable, as the case may be, have been proportionately decreased on a 1-for-6 basis, (iii) the exercise price for each such outstanding option or warrant to purchase common stock has been proportionately increased on a 6-for-1 basis, and (iv) the conversion ratio for each share of preferred stock outstanding was proportionately reduced on a 1-for-6 basis. All of the share numbers, share prices, and exercise prices have been adjusted within these financial statements, on a retroactive basis, to reflect this 1-for-6 reverse stock split. The Company paid cash in lieu of any fractional shares to which a holder of common stock would otherwise be entitled as a result of the reverse stock split.
	On August 12, 2013, the Company closed the IPO of its common stock pursuant to a registration statement on Form S-1. In the IPO, the Company sold 5,125,000 shares of common stock at a public offering price of $9.00 per share. Net proceeds were approximately $40.0 million, after deducting underwriting discounts and commissions of $3.2 million and offering expenses of $2.9 million. Upon the closing of the IPO, all outstanding shares of the Company’s convertible preferred stock automatically converted into 21,840,537 shares of common stock and all outstanding warrants to purchase convertible preferred stock converted into warrants to purchase 53,983 shares of common stock.
	Basis of Consolidation
	The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
	Certain Significant Risks and Uncertainties
	The Company operates in a dynamic industry and, accordingly, can be affected by a variety of factors. For example, the Company believes that changes in any of the following areas could have a significant negative effect on its future financial position, results of operations, or cash flows: rates of revenue growth; traffic to and pricing with the Company's network of digital media property owners; scaling and adaptation of existing technology and network infrastructure; adoption of the Company’s product and solution offerings; management of the Company's growth; new markets and international expansion; protection of the Company's brand, reputation and intellectual property; competition in the Company's markets; recruiting and retaining qualified employees and key personnel; intellectual property infringement and other claims; and changes in government regulation affecting the Company's business, among other things.

Note_2_Summary_of_Significant_

Note 2 - Summary of Significant Accounting Policies	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	2	Summary of Significant Accounting Policies
	Use of Estimates
	The preparation of the Company's consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of the financial statements and the reported amounts of income and expenses during the reporting period. These estimates are based on information available as of the date of the financial statements; therefore, actual results could differ from management's estimates.
	Foreign Currency Translation and Transactions
	The consolidated financial statements of the Company's foreign subsidiaries are measured using the local currency as the functional currency, except for India and France, which have U.S. dollar and British pound sterling functional currencies, respectively. Assets and liabilities of foreign subsidiaries are translated at exchange rates in effect as of the balance sheet date. Revenues and expenses are translated at average exchanges rates in effect during the period. Translation adjustments are recorded within accumulated other comprehensive loss, a separate component of stockholders' equity, on the consolidated balance sheets. Foreign exchange transaction gains and losses have not been material to the Company's consolidated financial statements for all periods presented.
	Cash and Cash Equivalents
	To date, the Company invests its excess cash in money market funds. The Company considers all highly liquid financial instruments purchased with original maturities of three months or less to be cash equivalents.
	Marketable Securities
	The Company began investing its cash and cash equivalents in marketable securities during the fourth quarter of 2013. Marketable securities are classified as available-for-sale and have consisted of highly liquid corporate bonds, commercial paper and certificates of deposits that comply with the Company’s minimum credit rating policy. Short-term marketable securities consist of investments with final maturities of at least three months from the date of purchase that the Company intends to own for up to 12 months. Long-term marketable securities consist of investments with final maturities of more than 12 months from the date of purchase that the Company intends to own for more than 12 months, but not more than 24 months. By policy, the final maturity for each security within the portfolio shall not exceed 24 months from the date of purchase and the weighted average maturity of the portfolio shall not exceed 12 months at any point in time. Marketable securities are carried at fair value with unrealized gains and losses, net of taxes, reported as a component of stockholders’ equity on the consolidated balance sheets. See Note 4 for additional information regarding the Company’s marketable securities.
	Restricted Cash
	The lease agreement for the Company's New York office requires a security deposit to be maintained in the form of an unconditional, irrevocable letter of credit issued to the benefit of the landlord. The letter of credit is subject to renewal annually until the lease expires in March 2016. As of December 31, 2014 and 2013, the Company had letters of credit totaling $0.3 million included in restricted cash in the consolidated financial statements.
	Concentrations and Other Risks
	Financial instruments that subject the Company to a concentration of credit risk consist of cash and cash equivalents, marketable securities and accounts receivable. Cash and cash equivalents are deposited with one domestic and five foreign highly rated financial institutions and cash equivalents are invested in highly rated money market funds. Periodically, such balances may be in excess of federally insured limits. Marketable securities consist of highly liquid corporate bonds, commercial paper and certificates of deposits that comply with the Company’s minimum credit rating policy.
	Except for the Company’s single largest advertising agency customer noted below, credit risk with respect to accounts receivable is dispersed due to the large number of advertising customers. Collateral is not required for accounts receivable. The Company performs ongoing credit evaluations of customers’ financial condition and periodically evaluates its outstanding accounts receivable and establishes an allowance for doubtful accounts receivable based on the Company’s historical experience, the current aging and circumstances of accounts receivable and general industry and economic conditions. Accounts receivable are written off by the Company when it has been determined that all available collection avenues have been exhausted. In 2014, bad debt write-offs totaled $0.7 million. Prior to 2014, write-offs for uncollectible accounts have not been significant. However, if circumstances change, higher than expected bad debts may result in future write-offs that are greater than the Company’s estimates.
	The following table presents the changes in the allowance for doubtful accounts receivable (in thousands):
			Years Ended December 31,
			2014			2013		2012
	Allowance for doubtful accounts receivable:
	Balance - beginning of period		$	1,056		$	563	$	170
	Allowance for doubtful accounts receivable			1,154			493		393
	Doubtful accounts receivable write-offs			(739	)		-		-
	Balance - end of period		$	1,471		$	1,056	$	563
	The Company wrote-off $0.7 million of doubtful accounts receivable as bad debt during the year ended December 31, 2014. The Company did not write-off any doubtful accounts receivable as bad debt during the years ended December 31, 2013 and 2012.
	One advertising agency customer accounted for 8%, 19% and 21% of the Company’s revenue in 2014, 2013 and 2012, respectively. The same customer accounted for 9% and 17% of the Company’s accounts receivable as of December 31, 2014 and 2013, respectively.
	Property, Equipment and Software
	Property and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets, which are generally three to five years. Leasehold improvements are amortized over the shorter of the asset life or remaining lease term.
	Internal-Use Software Development Costs
	The Company capitalizes the costs to develop internal-use software when preliminary development efforts are successfully completed, it has authorized and committed project funding, and it is probable that the project will be completed and the software will be used as intended. Such costs are amortized on a straight-line basis over the estimated useful life of the software, which approximates three years. Costs incurred prior to meeting these criteria, together with costs incurred for training and maintenance, are expensed as incurred. Costs incurred for upgrades and enhancements that are expected to result in additional material functionality are capitalized and amortized over the respective estimated useful life.
	The Company capitalized $2.4 million, $2.0 million and $0.8 million of internal-use software costs during the years ended December 31, 2014, 2013 and 2012, respectively, which are included in property, equipment and software on the consolidated balance sheets. Amortization expense totaled approximately $1.1 million, $1.0 million and $0.9 million for the years ended December 31, 2014, 2013 and 2012, respectively.
	Impairment of Long-lived Assets
	The Company evaluates its long-lived assets for impairment when circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported as a separate caption at the lower of the carrying amount or fair value less costs to sell. There were no impairment charges recorded or changes in estimated useful lives during years ended December 31, 2014, 2013 and 2012.
	Deferred Offering Costs
	Deferred offering costs consisted primarily of direct incremental costs related to the Company's IPO. Upon completion of the IPO in August 2013, these amounts were offset against the proceeds of the offering. Consequently, there were no deferred offering costs included on the Company’s consolidated balance sheets as of December 31, 2013 or 2014.
	Deferred Rent
	The Company leases facilities worldwide under non-cancelable operating leases that expire through August 2024. These leases contain various renewal options. The Company recognizes rent holidays and escalating rent provisions on a straight-line basis over the term of the lease. The Company's deferred rent liability related to these facilities was approximately $0.3 and $0.2 million at December 31, 2014 and 2013, respectively, which are included in “Accrued liabilities” and “Other long-term liabilities” on the consolidated balance sheets.
	Revenue Recognition
	The Company's revenue is principally derived from advertising services measured by the number of advertising impressions displayed on digital media properties owned and controlled by third party digital media property owners and primarily priced on a cost per thousand impressions (“CPM”) basis. The Company recognizes revenue when: (1) persuasive evidence exists of an arrangement with the customer reflecting the terms and conditions under which products or services will be provided; (2) delivery has occurred or services have been provided; (3) the fee is fixed or determinable; and (4) collection is reasonably assured. For all revenue transactions, the Company considers a signed agreement, a binding insertion order or other similar documentation to be persuasive evidence of an arrangement. Arrangements for these services generally have a term of up to three months. In some cases the term may be up to one year or more.
	In the normal course of business, the Company acts as a facilitator in executing transactions with third parties. The determination of whether revenue should be reported on a gross or net basis is based on an assessment of whether the Company is acting as the principal or an agent in the transaction. In determining whether the Company acts as the principal or an agent, the Company follows the accounting guidance for principal-agent considerations. While none of the factors identified in this guidance is individually considered presumptive or determinative, because the Company is the primary obligor and is responsible for (i) identifying and contracting with third party advertisers, (ii) establishing the selling prices of the advertisements sold, (iii) performing all billing and collection activities including retaining credit risk and (iv) bearing sole responsibility for fulfillment of the advertising, which may also include committing to buy advertising inventory in advance, the Company acts as the principal in these arrangements and therefore reports revenue earned and costs incurred on a gross basis.
	The Company recognizes revenue based on delivery information from a combination of third party reporting and the Company's proprietary campaign tracking systems.
	Multiple-element Arrangements
	The Company enters into arrangements with customers to sell advertising packages that include different media placements or ad services that are delivered at the same time, or within close proximity of one another.
	At the inception of an arrangement, the Company allocates arrangement consideration in multiple-deliverable revenue arrangements to all deliverables, based on the relative selling price method in accordance with the selling price hierarchy, which includes: (1) vendor-specific objective evidence (“VSOE”) if available; (2) third party evidence (“TPE”) if VSOE is not available; and (3) best estimate of selling price (“BESP”) if neither VSOE nor TPE is available.
	VSOE—The Company evaluates VSOE based on its historical pricing and discounting practices for the specific product or service when sold separately. In determining VSOE, the Company requires that a substantial majority of the standalone selling prices for these services fall within a reasonably narrow pricing range. The Company historically has not entered into a large volume of single-element arrangements, so it has not been able to establish VSOE for any of its advertising products.
	TPE—When VSOE cannot be established for deliverables in multiple element arrangements, the Company applies judgment with respect to whether it can establish a selling price based on TPE. TPE is determined based on competitor prices for similar deliverables when sold separately. Generally, the Company's go-to-market strategy differs from that of its peers and its offerings contain a significant level of differentiation such that the comparable pricing of services cannot be obtained. Furthermore, the Company is unable to reliably determine what similar competitor services' selling prices are on a standalone basis. As a result, the Company has not been able to establish selling price based on TPE.
	BESP—When the Company is unable to establish selling price using VSOE or TPE, the Company uses BESP in its allocation of arrangement consideration. The objective of BESP is to determine the price at which the Company would transact a sale if the service were sold on a standalone basis. BESP is generally used to allocate the selling price to deliverables in the Company's multiple-element arrangements. The Company determines BESP for deliverables by considering multiple factors including, but not limited to, prices it charges for similar offerings, class of advertiser, size of transaction, seasonality, observed pricing trends, available online inventory, industry pricing strategies, market conditions and competitive landscape. The Company limits the amount of allocable arrangement consideration to amounts that are fixed or determinable and that are not contingent on future performance or future deliverables. The Company periodically reviews its BESP. Changes in assumptions or judgments or changes to the elements in the arrangement could cause a material increase or decrease in the amount of revenue that the Company reports in a particular period.
	The Company recognizes the relative fair value of the media placements or ad services as they are delivered assuming all other revenue recognition criteria are met. Deferred revenue is comprised of contractual billings in excess of recognized revenue and payments received in advance of revenue recognition.
	Cost of revenue
	Cost of revenue consists of amounts incurred with digital media property owners that are directly related to a revenue-generating event, direct labor costs, amortization of revenue-producing acquired technologies, Internet access costs and depreciation expense. The Company incurs costs with digital media property owners in the period the advertising impressions are delivered or in limited circumstances, based on minimum guaranteed number of impressions. Such amounts incurred are classified as cost of revenue in the corresponding period in which the revenue is recognized in the consolidated statements of operations.
	Advertising expense
	The Company's advertising costs are expensed as incurred. The Company incurred approximately $1.7 million, $1.5 million and $0.6 million in advertising expenses for the years ended December 31, 2014, 2013 and 2012, respectively.
	Comprehensive Income (Loss)
	Comprehensive income (loss) consists of net income (loss) and changes in accumulated other comprehensive income (loss), which are primarily the result of foreign currency translation adjustments and unrealized gains or losses on marketable securities, net of tax.
	Stock-based Compensation
	The Company measures compensation expense for all stock-based payment awards, including stock options granted to employees, directors and non-employees based on the estimated fair values on the date of the grant. The fair value of each stock option granted is estimated using the Black-Scholes option valuation model. Stock-based compensation expense related to restricted stock units (“RSUs”) is based on the grant date fair value of the RSUs. Stock-based compensation is recognized on a straight-line basis over the requisite service period.
	Stock-based compensation expense is recorded net of estimated forfeitures in our consolidated statements of income and as such is recorded for only those share-based awards that we expect to vest. The Company estimates the forfeiture rate based on historical forfeitures of equity awards and adjusts the rate to reflect changes in facts and circumstances, if any. The Company will revise our estimated forfeiture rate if actual forfeitures differ from our initial estimates.
	Goodwill
	Goodwill is not amortized, but is tested for impairment at least annually or as circumstances indicate the value may no longer be recoverable. The Company evaluates goodwill for impairment annually in the fourth quarter of its fiscal year or, whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable. Triggering events that may indicate impairment include, but are not limited to, a significant adverse change in customer demand or business climate that could affect the value of goodwill or a significant decrease in expected cash flows. Through December 31, 2014, no impairment of goodwill has been identified.
	The FASB issued an accounting standard update that permits entities to first assess qualitative factors to determine whether it is more likely than not (a likelihood of more than 50%) that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. This new guidance was adopted by the Company on January 1, 2012 on a prospective basis and the adoption of did not materially impact the Company’s consolidated financial statements. As of December 31, 2014 and 2013, the Company elected to first assess qualitative factors to determine whether it is necessary to perform the two-step annual goodwill impairment test. The Company assessed qualitative factors including its market capitalization, stock price, industry and market conditions, cost factors and cash flows and concluded that it was more likely than not that the fair value of its sole reporting unit is greater than the carrying value of goodwill.
	Intangible Assets
	Acquired intangible assets consist of acquired customer relationships, developed technology and non-compete agreements. Acquired intangible assets are recorded at fair value, net of accumulated amortization. Intangible assets are amortized on a straight-line basis over their estimated useful lives. The Company reviews identifiable amortizable intangible assets to be held and used for impairment whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. Determination of recoverability is based on the lowest level of identifiable estimated undiscounted cash flows resulting from use of the asset and its eventual disposition. Measurement of any impairment loss is based on the excess of the carrying value of the asset over its fair value. Through December 31, 2014, no impairment of intangibles has been identified.
	Preferred Stock Warrant Liability
	Prior to our IPO on August 7, 2013, freestanding warrants related to shares of the Company’s preferred stock that were contingently redeemable were classified as a liability on the Company's consolidated balance sheet. The convertible preferred stock warrants were subject to re-measurement at each balance sheet date up to the date of our IPO and any changes in fair value were recognized as a component of “Other income (expense), net.” As of August 7, 2013, all redeemable convertible preferred stock warrants were converted into warrants to purchase common stock and the liability of $0.4 million was reclassified to additional paid-in capital.
	Income Taxes
	The Company records income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company's consolidated financial statements or income tax returns. In estimating future tax consequences, expected future events other than enactments or changes in the tax law or rates are considered. Valuation allowances are provided when necessary to reduce deferred tax assets to the amount expected to be realized.
The Company operates in various tax jurisdictions and is subject to audit by various tax authorities. The Company provides for tax contingencies whenever it is deemed probable that a tax asset has been impaired or a tax liability has been incurred for events such as tax claims or changes in tax laws. Tax contingencies are based upon their technical merits, relative tax law, and the specific facts and circumstances as of each reporting period. Changes in facts and circumstances could result in material changes to the amounts recorded for such tax contingencies.
The Company records uncertain tax positions in accordance with accounting standards on the basis of a two-step process whereby (1) a determination is made as to whether it is more likely than not that the tax positions will be sustained based on the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold the Company recognizes the largest amount of tax benefit that is greater than 50% likely to be realized upon ultimate settlement with the related tax authority.
Recently Issued Accounting Standards
In February 2013, the FASB issued Accounting Standards Updates (“ASU”) 2013-2, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified out of Accumulated Other Comprehensive Income (ASU 2013-2), to improve the reporting of reclassifications out of accumulated other comprehensive income. ASU 2013-2 requires presentation, either on the face of the financial statements or in the notes, of amounts reclassified out of accumulated other comprehensive income by component and by net income line item. ASU 2013-2 is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2012. The Company adopted ASU 2013-2 in the first quarter of fiscal 2014. The adoption of ASU 2013-2 did not have a significant impact on the Company's consolidated financial statements.
In July 2013, the FASB issued amended standards that provided explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward or a tax credit carryforward exists. The new guidance provides that a liability related to an unrecognized tax benefit would be presented as a reduction of a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward, if such settlement is required or expected in the event the uncertain tax position is disallowed. The new guidance became effective on January 1, 2014 and should be applied prospectively to unrecognized tax benefits that exist at the effective date with retrospective application permitted. The adoption of these amended standards did not have a significant impact on the Company’s financial position, results of operations, or cash flows.
In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which amends the existing accounting standards for revenue recognition. ASU 2014-09 is based on principles that govern the recognition of revenue at an amount to which an entity expects to be entitled when products are transferred to customers. ASU 2014-09 will be effective for the Company beginning in its first quarter of 2017. Early adoption is not permitted. The new revenue standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. The Company has not yet selected a transition method and is currently evaluating the impact of adopting the new revenue standard on its consolidated financial statements.

Business Combinations [Abstract]
Business Combination Disclosure [Text Block]	3	Acquisition
	Crowd Science, Inc.
	On December 28, 2012, the Company completed the acquisition of Crowd Science, Inc. (“Crowd Science”), a technology company providing online digital media properties audience measurement, ad targeting and web analytics. All of the share capital for Crowd Science was acquired in exchange for $1.1 million in cash and 2,000,000 shares of Series D-1 convertible preferred stock valued at $3.3 million, for a total consideration of $4.4 million. The Company held back $49,000 in cash and 400,000 shares of Series D-1 convertible preferred stock classified as contingent consideration to non-employee stockholders at the closing of the acquisition until the second anniversary of the closing date for general representations and warranties as well as performance conditions tied to the expected continuing employment of key employees. The goodwill generated from the Company's business combination is primarily related to expected synergies. The goodwill is deductible for U.S. federal income tax purposes.
	The fair value of the Series D-1 convertible preferred stock of $1.67 per share was based on management's contemporaneous valuation of the Company as of December 28, 2012, the date of acquisition. In determining the enterprise equity value of the Company, management used a valuation methodology based on the income approach and the market approach utilizing guideline public companies. Once an enterprise equity value was calculated, management used the option pricing method to allocate the value to each series of preferred stock and common stock which generated a value of $1.67 per share of Series D-1 preferred stock.
	As a condition to its acquisition of Crowd Science, the parties agreed that all amounts held back by the Company at closing, consisting of $49,000 in cash and 400,000 shares of Series D-1 convertible stock, may be permanently withheld by the Company if any key employee (identified in the acquisition agreement) were to voluntarily terminate his employment with the Company within the first year after closing of the acquisition. The performance conditions were not met during 2013. As such, the Company accounted for the settlement of this contingent consideration within equity during 2013. The Company’s 1-for-6 reverse stock split effective July 2013 and the conversion of preferred stock to common stock associated with the Company’s IPO in August 2013 resulted in the number of shares permanently held back by the Company to become 66,666 common stock shares. The Company accounts for the withheld shares as 66,666 shares of treasury stock.
	The acquisition was accounted for as a business combination in accordance with ASC 805 with the results of the acquired company's operations included in the consolidated financial statements starting on December 28, 2012. The key factors underlying the acquisition were to acquire technology that would enhance audience reach and targeting across all video devices.

Note_5_Fair_Value_of_Financial

Note 5 - Fair Value of Financial Instruments	12 Months Ended
	Dec. 31, 2014
Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	5	Fair Value of Financial Instruments
	The accounting guidance for fair value measurements prioritizes the inputs used in measuring fair value in the following hierarchy:
		Level 1 -	Unadjusted quoted prices in active markets for identical assets or liabilities;
		Level 2 -	Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and
		Level 3 -	Unobservable inputs for which there is little or no market data, which require the Company to develop its own assumptions.
	A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The carrying amounts of accounts receivable, accounts payable and accrued liabilities, approximate fair value due to their relatively short maturities.
	Prior to the conversion of the Company’s warrant liability on August 12, 2013, its preferred stock warrants were recorded at fair value. On August 12, 2013, upon the closing of the Company’s IPO, the warrants were converted from warrants to purchase preferred stock to warrants to purchase common stock and the liability at their then fair value of $0.4 million was reclassified to additional paid-in capital. Prior to this date, all changes in the fair value of the warrants were recorded in “Other income (expense), net” in the consolidated statements of operations. The fair value of the warrants outstanding, which were remeasured to fair value on a recurring basis at each balance sheet date, was determined using the Black-Scholes option pricing model. See Note 11 for additional information. The Company recorded other income of $0.1 million in both 2013 and 2012, respectively, related to the fair value adjustment of its warrants.
	Marketable securities with final maturities of at least three months but no more than 12 months from the date of purchase are classified as short-term and marketable securities with final maturities of more than one year but less than two years from the date of purchase are classified as long-term. Our marketable securities are classified as available-for-sale and consist of high quality, investment grade securities from diverse issuers with predetermined minimum credit ratings. The Company values these securities based on pricing from pricing vendors who may use quoted prices in active markets for identical assets (Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs) in determining fair value. However, the Company classifies all of its marketable securities as having Level 2 inputs. The valuation techniques used to measure the fair value of the Company’s marketable securities having Level 2 inputs were derived from market prices that are corroborated by observable market data and quoted market prices for similar instruments.
	The following tables present information about the Company’s money market funds and marketable securities measured at fair value on a recurring basis as of December 31, 2014 and 2013 and indicates the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value (in thousands):

	In November 2014, the Company entered into a Loan and Security Agreement with Silicon Valley Bank (“SVB”) to borrow up to a maximum of $25.0 million collateralized by the Company’s cash deposits, accounts receivable and equipment, as well as certain other assets. The Loan and Security Agreement requires the Company to comply with certain financial and reporting covenants, including maintaining an adjusted quick ratio of 1.4 to 1.0. Annual fees under the agreement total one quarter of 1.0% of the average unused balance of the credit line per annum. As of December 31, 2014, the Company had no borrowings outstanding under this credit line.
	In connection with a previous Loan and Security Agreement with SVB that expired on May 3, 2013, the Company issued warrants to SVB to purchase 29,145 shares of Series C preferred stock, of which warrants to purchase 14,573 shares were issued September 25, 2009 and warrants to purchase 14,572 shares were issued January 27, 2010.

Stockholders' Equity Note Disclosure [Text Block]	11	Convertible Preferred Stock and Stockholders’ Equity
	Initial Public Offering
	On August 12, 2013, the Company closed its IPO in which it sold 5,125,000 shares of common stock at a public offering price of $9.00 per share. The aggregate offering price for shares sold in the offering was approximately $46.1 million. Net proceeds were approximately $40.0 million, after deducting underwriting discounts and commissions of $3.2 million and offering expenses of $2.9 million.
	Convertible Preferred Stock
	Convertible preferred stock as of December 31, 2012 and immediately prior to the IPO consisted of the following:
	Convertible Preferred Stock		Shares				Shares Issued and			Issuance Price			Carrying		Liquidation

		-1	Amounts are presented without giving effect to the Company’s 1-for-6 reverse stock split that was effective July 24, 2013, as the number of convertible preferred stock shares did not change.
		-2	Amounts are net of issuance costs.
	Balance Sheet Presentation
	Upon the closing of the IPO on August 7, 2013, all outstanding shares of the Company’s convertible preferred stock automatically converted into 21,840,537 shares of common stock and the carrying value of $76.2 million is included in additional paid-in capital on the consolidated balance sheet as of December 31, 2014 and 2013.
	Immediately following the closing of the IPO, the Company’s certificate of incorporation was amended to authorize 20,000,000 shares of undesignated preferred stock and 200,000,000 shares of common stock.
	Preferred Stock
	In association with our IPO, our board of directors authorized the Company to issue up to 20,000,000 shares of preferred stock, par value $0.001 per share. As of December 31, 2014 and 2013, no shares of preferred stock were outstanding.
	Common Stock
	At December 31, 2014 and 2013 there were 33,066,327 and 31,933,862 shares of common stock issued and outstanding, respectively. The following table summarizes common stock activity during the year ended December 31, 2014:
			Number of Shares
	Outstanding at December 31, 2013			31,933,862
	Option exercises			801,691
	RSUs vesting			15,450
	Common stock issued in connection with employee stock purchase plan			315,324
	Outstanding at December 31, 2014			33,066,327
	Treasury Stock
	The Company has 66,666 shares of treasury stock related to the acquisition of Crowd Science. Treasury stock is carried at cost and could be re-issued if the Company determined to do so. See Note 3 for additional information on Crowd Science withheld shares.
	Equity Incentive Plans
	The Company’s 2004 Stock Plan (the “2004 Plan”) authorized the Company to grant restricted stock awards or stock options to employees, directors and consultants at prices not less than the fair market value at date of grant for incentive stock options and not less than 85% of fair market value for non-statutory options. Option vesting schedules were determined by the board of directors at the time of issuance and they generally vest at 25% on the first anniversary of the grant (or the employment or service commencement date) and monthly over the next 36 months. Options generally expire ten years from the date of grant unless the optionee is a 10% stockholder, in which case the term will be five years from the date of grant. Unvested options exercised are subject to the Company’s repurchase right. Upon the effective date of the registration statement related to the Company’s IPO, the 2004 Plan was amended to cease the grant of any additional awards thereunder, although the Company will continue to issue common stock upon the exercise of stock options previously granted under the 2004 Plan.
	In July 2013, the Company adopted a 2013 Equity Incentive Plan (the “2013 Plan”) which became effective on August 6, 2013. The 2013 Plan serves as the successor equity compensation plan to the 2004 Plan. The 2013 Plan will terminate on July 23, 2023. The 2013 Plan provides for the grant of incentive stock options, nonqualified stock options, restricted stock awards, stock appreciation rights, performance stock awards, restricted stock units and stock bonus awards to employees, directors and consultants. Stock options granted must be at prices not less than 100% of the fair market value at date of grant. Option vesting schedules are determined by the Company at the time of issuance and they generally vest at 25% on the first anniversary of the grant (or the employment or service commencement date) and monthly over the next 36 months. Options generally expire ten years from the date of grant unless the optionee is a 10% stockholder, in which case the term will be five years from the date of grant. Unvested options exercised are subject to the Company’s repurchase right. The Company initially reserved 2,000,000 shares of its common stock for issuance under the 2013 Plan, and shares reserved for issuance increase January 1 of each year by the lesser of (i) 5% of the number of shares issued and outstanding on December 31 immediately prior to the date of increase or (ii) such number of shares as may be determined by the board of directors.
	Prior to the IPO, the fair value of the common stock underlying the Company’s stock options was determined by the Company’s board of directors, which intended all options granted to be exercisable at a price per share not less than the per-share fair value of the Company’s common stock underlying those options on the date of grant. The valuations of the Company’s common stock were determined in accordance with the guidelines outlined in the American Institute of Certified Public Accountants Practice Aid, Valuation of Privately-Held-Company Equity Securities Issued as Compensation. The assumptions the Company used in the valuation model are based on future expectations combined with management judgment. In the absence of a public trading market, the Company’s board of directors, with input from management, exercised significant judgment and considered numerous objective and subjective factors to determine the fair value of the Company’s common stock as of the date of each option grant. Subsequent to the IPO, the fair value of the common stock underlying the Company’s stock options is the closing price of the Company’s stock as of the grant date.
	The following table summarizes option activity:
			Number of Shares				Weighted-Average Exercise Price			Weighted-Average Remaining Contractual Life			Aggregate Intrinsic Value (2)

	The weighted average grant date fair value of options granted was $3.76, $5.89 and $3.06 in 2014, 2013 and 2012, respectively. Prior to the Company’s IPO, aggregate intrinsic value represented the difference between the Company’s estimated fair value of its common stock and the exercise price of outstanding, in-the-money options. After the Company’s IPO, aggregate intrinsic value represents the difference between the market value of the Company’s common stock and the exercise price of outstanding, in-the-money options. The total intrinsic value of options exercised was approximately $2.0 million, $1.3 million and $3.4 million for 2014, 2013 and 2012, respectively.

	-1	The intrinsic value of RSUs is based on the Company’s closing stock price as reported by the New York Stock Exchange on December 31, 2013 and 2014.
The Company did not grant any RSUs prior to 2013. The total grant date fair value of restricted stock units vested during the year ended December 31, 2014 was $0.1 million. All of our RSUs that were settled during the years ended December 31, 2014 and 2013 were net share settled. As such, upon each settlement date, RSUs were withheld to cover the required withholding tax, which is based on the value of the RSU on the settlement date as determined by the closing price of our common stock on the trading day of the settlement date. The remaining amounts are delivered to the recipient as shares of our common stock.
Employee Stock Purchase Plan
In July 2013, the Company adopted a 2013 Employee Stock Purchase Plan (the “2013 Purchase Plan”) that became effective on August 6, 2013. The 2013 Purchase Plan is designed to enable eligible employees to periodically purchase shares of the Company’s common stock at a discount through payroll deductions of up to 15% of their eligible compensation, subject to any plan limitations. At the end of each offering period, employees are able to purchase shares at 85% of the lower of the fair market value of the Company’s common stock on the first trading day of the offering period or on the last day of the offering period. Purchases are accomplished through participation in discrete offering periods. The 2013 Purchase Plan is intended to qualify as an employee stock purchase plan under Section 423 of the Internal Revenue Code. The Company initially reserved 500,000 shares of its common stock for issuance under the 2013 Purchase Plan and shares reserved for issuance increase January 1 of each year by the lesser of (i) a number of shares equal to 1% of the total number of outstanding shares of common stock on December 31 immediately prior to the date of increase or (ii) such number of shares as may be determined by the board of directors.
The expected term of ESPP shares is the average of the remaining purchase periods under each offering period. The assumptions used to value employee stock purchase rights were as follows:
		Year Ended			Year Ended
		31-Dec-14			31-Dec-13
Expected term (years)		0.5			0.47
Volatility		80%			80%
Risk-free interest rate		0.05%-0.08%			0.08%
Dividend yield		—			—
Shares Reserved for Future Issuance
At December 31, 2014 and 2013, the Company has reserved the following shares of common stock for future issuance:
		December 31,
		2014				2013
Common stock reserved:
Common stock options			5,058,641				5,713,106
Restricted stock units			1,082,939				38,124
Warrants to purchase common stock			24,838				24,838
Shares available for future issuance under the 2013 Plan			984,455				936,457
Employee stock purchase plan			504,014				500,000
			7,654,887				7,212,525
Stock-Based Compensation
The fair value of options granted to employees is estimated on the grant date using the Black-Scholes option valuation model. This valuation model for stock-based compensation expense requires the Company to make assumptions and judgments about the variables used in the calculation including the expected term (weighted-average period of time that the options granted are expected to be outstanding), volatility of the Company’s common stock, a risk-free interest rate, expected dividends, and the estimated forfeitures of unvested stock options. To the extent actual results differ from the estimates, the difference will be recorded as a cumulative adjustment in the period estimates are revised. The Company uses the simplified calculation of expected life, and volatility is based on an average of the historical volatilities of the common stock of a group of entities with characteristics similar to those of the Company. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the option. Expected forfeitures are based on the Company’s historical experience. The Company currently has no history or expectation of paying cash dividends on common stock.
The fair value of options granted to employees is determined using the Black-Scholes option valuation model with the following assumptions:
		Years Ended December 31,
		2014			2013			2012
Expected term (years)		6			5.51-6.12			5.60-6.07
Volatility		80%			80%			65% - 90%
Risk-free interest rate		1.74%-2.02%			1.06%-1.72%			0.73%-1.09%
Dividend yield		—			—			—
Weighted-average fair value		$3.76			$5.89			$3.06
Stock Options Granted to Non-employees
For the year ended December 31, 2012, 8,333 options were granted to non-employees. There were no options granted to non-employees during the years ended December 31, 2014 and 2013.
The Company accounts for stock options issued to non-employees in accordance with the provisions of ASC 505-50 using a fair value approach. The measurement of stock based compensation for non-employees is subject to period adjustments as the options vest and the expense is recognized over the period which services are received. The Company believes that the fair value of the stock options is more reliably measurable than the fair value of the services received. The estimated fair value of the stock options granted to non-employees was calculated using the following assumptions:
		Years Ended December 31,
		2014				2013			2012
Expected term (years)			6				8.24			9.65
Volatility			80	%			80	%		80	%
Risk-free interest rate			2.02	%			2.64	%		1.7	%

No income tax benefit has been recognized relating to stock-based compensation expense and no tax benefits have been realized from exercised stock options during the years ended December 31, 2014, 2013 and 2012. As of December 31, 2014, there was $11.6 million of unrecognized compensation cost, adjusted for estimated forfeitures, related to non-vested stock-based awards which will be recognized over a weighted average period of 2.46 years. Total unrecognized compensation cost will be adjusted for future changes in estimated forfeitures.
Warrants
In conjunction with a lease agreement, the Company issued warrants to purchase 24,838 shares of Series A-2 preferred stock on December 31, 2006. These warrants have an exercise price of $1.2078 per share and expire on December 31, 2018. On August 12, 2013, upon the closing of the Company’s IPO, the warrants were converted from warrants to purchase preferred stock to warrants to purchase common stock and the liability at their then fair value of $0.4 million was reclassified to additional paid-in capital. Prior to the conversion of the warrant liability on August 12, 2013, the Company’s preferred stock warrants were recorded at fair value. Changes in the fair value of the warrants were recorded in “Other income (expense), net” in the consolidated statements of operations. The Company recorded other expense of $0.1 million for both 2013 and 2012 related to changes in the fair value adjustment of these warrants.
The fair value of the warrants outstanding which, prior to the closing of the Company’s IPO on August 12, 2013, were recorded as liabilities on the consolidated balance sheets and which were remeasured to fair value on a recurring basis at each balance sheet date, were determined using the Black-Scholes option pricing model with the following assumptions:
		Year 2013 through			Year Ended December
		12-Aug			31, 2012
Expected term (years)		3.41-5.76			4.01-6.00
Volatility		80%			80%
Risk-free interest rate		0.47% - 1.77%			0.54% - 0.95%
Dividend yield		—			—
A summary of the fair value of the warrants outstanding at December 31, 2012 and immediately prior to the closing of the Company’s IPO on August 12, 2013 are shown in the table below (in thousands):
		August 12,				December 31,
		2013				2012
Warrant (series A-2)		$	203			$	144
Warrant (series C)			223				157
Total fair value		$	426			$	301
The change in total fair value of the convertible preferred stock warrants has been recorded as a component of “Other income (expense)” in the consolidated statements of operations. After the warrants were converted into warrants for common stock in association with the completion of the Company’s IPO in August 2013, the total fair value of the warrants is no longer subject to remeasurement.
A summary of the warrants to purchase common stock outstanding at December 31, 2014 and 2013 are shown below:

Earnings Per Share [Abstract]
Earnings Per Share [Text Block]	12	Net Income (Loss) per Share
	Basic and diluted net income (loss) per common share is presented in conformity with the two-class method required for participating securities. Immediately prior to the closing of the Company’s IPO, all shares of outstanding convertible preferred stock automatically converted into shares of the Company’s common stock. Prior to the conversion of the convertible preferred stock, holders of Series A-1, Series A-2, Series B, Series C, Series D and Series D-1 convertible preferred stock were entitled to receive noncumulative dividends when and if declared at the annual rate of 8% ($0.10500, $0.20130, $0.54760, $0.28592, $1.00496 and $1.31370 per share per annum, respectively) payable prior, and in preference to, any dividends on any shares of the Company’s common stock. In the event a dividend was paid on common stock, the holders of Series A-1, Series A-2, Series B, Series C, Series D and Series D-1 convertible preferred stock were entitled to a proportionate share of any such dividend as if they were holders of common stock (on an as-if converted basis). The holders of convertible preferred stock did not have a contractual obligation to share in the losses of the Company, accordingly, basic and diluted net income (loss) per share has not been computed using the two class method.
	Under the two-class method, net income (loss) attributable to common stockholders is determined by allocating undistributed earnings, calculated as net income (loss) less current period convertible preferred stock non-cumulative dividends, between common stock and convertible preferred stock. In computing diluted net income (loss) attributable to common stockholders, undistributed earnings are re-allocated to reflect the potential impact of dilutive securities. Basic net income (loss) per common share is computed by dividing the net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share attributable to common stockholders is computed by dividing the net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding, including potential dilutive common shares assuming the dilutive effect of outstanding stock options using the treasury stock method.
	The following table presents the calculation of basic and diluted net income (loss) per share (in thousands, except per share data):

	The primary differences between the effective tax rates and the federal statutory tax rate relates to the valuation allowances on the Company's net operating losses, state income taxes, foreign tax rate differences and non-deductible stock-based compensation expense. The following table presents a reconciliation of the statutory federal rate and the Company's effective tax rate for the periods presented:

	Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The following table presents the significant components of the Company's deferred tax assets and liabilities for the periods presented (in thousands):

	Valuation allowance			(9,157	)		(7,524	)
	Total net deferred tax liabilities		$	(431	)	$	(773	)
	A valuation allowance is provided when it is more likely than not that the deferred tax assets will not be realized. As of December 31, 2014 and December 31, 2013, a full valuation allowance on domestic deferred tax assets was placed due to the uncertainty of realizing future tax benefits from its net operating loss carryforwards and other deferred tax assets. The Company’s valuation allowance as of December 31, 2014, 2013 and 2012 was attributable to the uncertainty of realizing future tax benefits from U.S. net operating losses, foreign timing differences and other deferred tax assets. The Company’s valuation allowance increased $1.6 million and $0.1 million in the years ended December 31, 2014 and 2013, respectively, and decreased $2.7 million in the year ended December 31, 2012.
	As of December 31, 2014, the Company has U.S. federal net operating loss carryforwards of approximately $9.5 million, expiring beginning in 2026. As of December 31, 2014, the Company has U.S. state and local net operating loss carryforwards of approximately $15.9 million, expiring beginning in 2016.
	As of December 31, 2014, the Company has federal research and development tax credits of approximately $0.8 million, which expire beginning in 2026. As of December 31, 2014, the Company has state research and development tax credits of approximately $0.7 million, and other tax credits of approximately $0.3 million, both of which carry forward indefinitely.
	Internal Revenue Code section 382 places a limitation (the “Section 382 Limitation”) on the amount of taxable income that can be offset by net operating carryforwards after a change in control of a loss corporation. Generally, after a change in control, a loss corporation cannot deduct operating loss carryovers in excess of the Section 382 Limitation. Management has determined that any limitation imposed by Section 382 will not have significant impact on the utilization of its net operating loss and credit carryforwards against taxable income in future periods.
	U.S. income and foreign withholding taxes associated with the repatriation of earnings of foreign subsidiaries have not been provided on undistributed earnings of foreign subsidiaries. The Company intends to reinvest theses earnings indefinitely outside the United States. If these earnings were distributed to the U.S. in the form of dividends or otherwise, or if the shares of the relevant subsidiaries were sold or otherwise transferred, the Company may be subject to additional U.S. income taxes (subject to an adjustment for foreign tax credits) and foreign withholding taxes; however, the determination of such amount is not practicable. As of December 31, 2014, the cumulative amount of earnings upon which U.S. income taxes have not been provided for is approximately $1.5 million.
	Uncertain Tax Positions
	A reconciliation of the beginning and ending balances of the unrecognized tax benefits during the years ended December 31, 2014, 2013 and 2012 consist of the following (in thousands):
			Years Ended December 31,
			2014			2013			2012
	Unrecognized benefit - beginning of period		$	358		$	246		$	158
	Gross increases - current year tax provisions			101			112			88
	Unrecognized benefit - end of period		$	459		$	358		$	246
	The entire amount of any unrecognized tax benefits would not impact the Company’s effective tax rate if recognized.
	Accrued interest and penalties related to unrecognized tax benefits are classified as income tax expense and were immaterial. The Company files income tax returns in the United States, various states and certain foreign jurisdictions. The tax periods 2010 through 2013 remain open in most jurisdictions. In addition, any tax losses and research and development credit carryforwards that were generated in prior years and carried forward may also be subject to examination by respective taxing authorities. The Company is not currently under examination by income tax authorities in federal, state or other foreign jurisdictions.

Accounting_Policies_by_Policy_

Accounting Policies, by Policy (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation
	The Company’s consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”).
	In July 2013, the Company's board of directors and stockholders approved an amendment to the amended and restated certificate of incorporation. The amendment provided for a 1-for-6 reverse stock split of the outstanding common stock, effective July 24, 2013. Accordingly, (i) every six shares of common stock were combined into one share of common stock, (ii) the number of shares of common stock into which each outstanding option or warrant to purchase common stock is exercisable, as the case may be, have been proportionately decreased on a 1-for-6 basis, (iii) the exercise price for each such outstanding option or warrant to purchase common stock has been proportionately increased on a 6-for-1 basis, and (iv) the conversion ratio for each share of preferred stock outstanding was proportionately reduced on a 1-for-6 basis. All of the share numbers, share prices, and exercise prices have been adjusted within these financial statements, on a retroactive basis, to reflect this 1-for-6 reverse stock split. The Company paid cash in lieu of any fractional shares to which a holder of common stock would otherwise be entitled as a result of the reverse stock split.
	On August 12, 2013, the Company closed the IPO of its common stock pursuant to a registration statement on Form S-1. In the IPO, the Company sold 5,125,000 shares of common stock at a public offering price of $9.00 per share. Net proceeds were approximately $40.0 million, after deducting underwriting discounts and commissions of $3.2 million and offering expenses of $2.9 million. Upon the closing of the IPO, all outstanding shares of the Company’s convertible preferred stock automatically converted into 21,840,537 shares of common stock and all outstanding warrants to purchase convertible preferred stock converted into warrants to purchase 53,983 shares of common stock.
Consolidation, Policy [Policy Text Block]	Basis of Consolidation
	The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Concentrations and Other Risks
	Financial instruments that subject the Company to a concentration of credit risk consist of cash and cash equivalents, marketable securities and accounts receivable. Cash and cash equivalents are deposited with one domestic and five foreign highly rated financial institutions and cash equivalents are invested in highly rated money market funds. Periodically, such balances may be in excess of federally insured limits. Marketable securities consist of highly liquid corporate bonds, commercial paper and certificates of deposits that comply with the Company’s minimum credit rating policy.
	Except for the Company’s single largest advertising agency customer noted below, credit risk with respect to accounts receivable is dispersed due to the large number of advertising customers. Collateral is not required for accounts receivable. The Company performs ongoing credit evaluations of customers’ financial condition and periodically evaluates its outstanding accounts receivable and establishes an allowance for doubtful accounts receivable based on the Company’s historical experience, the current aging and circumstances of accounts receivable and general industry and economic conditions. Accounts receivable are written off by the Company when it has been determined that all available collection avenues have been exhausted. In 2014, bad debt write-offs totaled $0.7 million. Prior to 2014, write-offs for uncollectible accounts have not been significant. However, if circumstances change, higher than expected bad debts may result in future write-offs that are greater than the Company’s estimates.
	The following table presents the changes in the allowance for doubtful accounts receivable (in thousands):
		Years Ended December 31,
		2014			2013		2012
	Allowance for doubtful accounts receivable:
	Balance - beginning of period	$	1,056		$	563	$	170
	Allowance for doubtful accounts receivable		1,154			493		393
	Doubtful accounts receivable write-offs		(739	)		-		-
	Balance - end of period	$	1,471		$	1,056	$	563
	The Company wrote-off $0.7 million of doubtful accounts receivable as bad debt during the year ended December 31, 2014. The Company did not write-off any doubtful accounts receivable as bad debt during the years ended December 31, 2013 and 2012.
	One advertising agency customer accounted for 8%, 19% and 21% of the Company’s revenue in 2014, 2013 and 2012, respectively. The same customer accounted for 9% and 17% of the Company’s accounts receivable as of December 31, 2014 and 2013, respectively.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates
	The preparation of the Company's consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of the financial statements and the reported amounts of income and expenses during the reporting period. These estimates are based on information available as of the date of the financial statements; therefore, actual results could differ from management's estimates.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Foreign Currency Translation and Transactions
	The consolidated financial statements of the Company's foreign subsidiaries are measured using the local currency as the functional currency, except for India and France, which have U.S. dollar and British pound sterling functional currencies, respectively. Assets and liabilities of foreign subsidiaries are translated at exchange rates in effect as of the balance sheet date. Revenues and expenses are translated at average exchanges rates in effect during the period. Translation adjustments are recorded within accumulated other comprehensive loss, a separate component of stockholders' equity, on the consolidated balance sheets. Foreign exchange transaction gains and losses have not been material to the Company's consolidated financial statements for all periods presented.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents
	To date, the Company invests its excess cash in money market funds. The Company considers all highly liquid financial instruments purchased with original maturities of three months or less to be cash equivalents.
Marketable Securities, Policy [Policy Text Block]	Marketable Securities
	The Company began investing its cash and cash equivalents in marketable securities during the fourth quarter of 2013. Marketable securities are classified as available-for-sale and have consisted of highly liquid corporate bonds, commercial paper and certificates of deposits that comply with the Company’s minimum credit rating policy. Short-term marketable securities consist of investments with final maturities of at least three months from the date of purchase that the Company intends to own for up to 12 months. Long-term marketable securities consist of investments with final maturities of more than 12 months from the date of purchase that the Company intends to own for more than 12 months, but not more than 24 months. By policy, the final maturity for each security within the portfolio shall not exceed 24 months from the date of purchase and the weighted average maturity of the portfolio shall not exceed 12 months at any point in time. Marketable securities are carried at fair value with unrealized gains and losses, net of taxes, reported as a component of stockholders’ equity on the consolidated balance sheets. See Note 4 for additional information regarding the Company’s marketable securities.
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]	Restricted Cash
	The lease agreement for the Company's New York office requires a security deposit to be maintained in the form of an unconditional, irrevocable letter of credit issued to the benefit of the landlord. The letter of credit is subject to renewal annually until the lease expires in March 2016. As of December 31, 2014 and 2013, the Company had letters of credit totaling $0.3 million included in restricted cash in the consolidated financial statements.
Property, Plant and Equipment, Policy [Policy Text Block]	Property, Equipment and Software
	Property and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets, which are generally three to five years. Leasehold improvements are amortized over the shorter of the asset life or remaining lease term.
Internal Use Software, Policy [Policy Text Block]	Internal-Use Software Development Costs
	The Company capitalizes the costs to develop internal-use software when preliminary development efforts are successfully completed, it has authorized and committed project funding, and it is probable that the project will be completed and the software will be used as intended. Such costs are amortized on a straight-line basis over the estimated useful life of the software, which approximates three years. Costs incurred prior to meeting these criteria, together with costs incurred for training and maintenance, are expensed as incurred. Costs incurred for upgrades and enhancements that are expected to result in additional material functionality are capitalized and amortized over the respective estimated useful life.
	The Company capitalized $2.4 million, $2.0 million and $0.8 million of internal-use software costs during the years ended December 31, 2014, 2013 and 2012, respectively, which are included in property, equipment and software on the consolidated balance sheets. Amortization expense totaled approximately $1.1 million, $1.0 million and $0.9 million for the years ended December 31, 2014, 2013 and 2012, respectively.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	Impairment of Long-lived Assets
	The Company evaluates its long-lived assets for impairment when circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported as a separate caption at the lower of the carrying amount or fair value less costs to sell. There were no impairment charges recorded or changes in estimated useful lives during years ended December 31, 2014, 2013 and 2012.
Deferred Charges, Policy [Policy Text Block]	Deferred Offering Costs
	Deferred offering costs consisted primarily of direct incremental costs related to the Company's IPO. Upon completion of the IPO in August 2013, these amounts were offset against the proceeds of the offering. Consequently, there were no deferred offering costs included on the Company’s consolidated balance sheets as of December 31, 2013 or 2014.
Deferred Rent [Policy Text Block]	Deferred Rent
	The Company leases facilities worldwide under non-cancelable operating leases that expire through August 2024. These leases contain various renewal options. The Company recognizes rent holidays and escalating rent provisions on a straight-line basis over the term of the lease. The Company's deferred rent liability related to these facilities was approximately $0.3 and $0.2 million at December 31, 2014 and 2013, respectively, which are included in “Accrued liabilities” and “Other long-term liabilities” on the consolidated balance sheets.
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition
	The Company's revenue is principally derived from advertising services measured by the number of advertising impressions displayed on digital media properties owned and controlled by third party digital media property owners and primarily priced on a cost per thousand impressions (“CPM”) basis. The Company recognizes revenue when: (1) persuasive evidence exists of an arrangement with the customer reflecting the terms and conditions under which products or services will be provided; (2) delivery has occurred or services have been provided; (3) the fee is fixed or determinable; and (4) collection is reasonably assured. For all revenue transactions, the Company considers a signed agreement, a binding insertion order or other similar documentation to be persuasive evidence of an arrangement. Arrangements for these services generally have a term of up to three months. In some cases the term may be up to one year or more.
	In the normal course of business, the Company acts as a facilitator in executing transactions with third parties. The determination of whether revenue should be reported on a gross or net basis is based on an assessment of whether the Company is acting as the principal or an agent in the transaction. In determining whether the Company acts as the principal or an agent, the Company follows the accounting guidance for principal-agent considerations. While none of the factors identified in this guidance is individually considered presumptive or determinative, because the Company is the primary obligor and is responsible for (i) identifying and contracting with third party advertisers, (ii) establishing the selling prices of the advertisements sold, (iii) performing all billing and collection activities including retaining credit risk and (iv) bearing sole responsibility for fulfillment of the advertising, which may also include committing to buy advertising inventory in advance, the Company acts as the principal in these arrangements and therefore reports revenue earned and costs incurred on a gross basis.
	The Company recognizes revenue based on delivery information from a combination of third party reporting and the Company's proprietary campaign tracking systems.
Multiple Element Arrangements [Policy Text Block]	Multiple-element Arrangements
	The Company enters into arrangements with customers to sell advertising packages that include different media placements or ad services that are delivered at the same time, or within close proximity of one another.
	At the inception of an arrangement, the Company allocates arrangement consideration in multiple-deliverable revenue arrangements to all deliverables, based on the relative selling price method in accordance with the selling price hierarchy, which includes: (1) vendor-specific objective evidence (“VSOE”) if available; (2) third party evidence (“TPE”) if VSOE is not available; and (3) best estimate of selling price (“BESP”) if neither VSOE nor TPE is available.
	VSOE—The Company evaluates VSOE based on its historical pricing and discounting practices for the specific product or service when sold separately. In determining VSOE, the Company requires that a substantial majority of the standalone selling prices for these services fall within a reasonably narrow pricing range. The Company historically has not entered into a large volume of single-element arrangements, so it has not been able to establish VSOE for any of its advertising products.
	TPE—When VSOE cannot be established for deliverables in multiple element arrangements, the Company applies judgment with respect to whether it can establish a selling price based on TPE. TPE is determined based on competitor prices for similar deliverables when sold separately. Generally, the Company's go-to-market strategy differs from that of its peers and its offerings contain a significant level of differentiation such that the comparable pricing of services cannot be obtained. Furthermore, the Company is unable to reliably determine what similar competitor services' selling prices are on a standalone basis. As a result, the Company has not been able to establish selling price based on TPE.
	BESP—When the Company is unable to establish selling price using VSOE or TPE, the Company uses BESP in its allocation of arrangement consideration. The objective of BESP is to determine the price at which the Company would transact a sale if the service were sold on a standalone basis. BESP is generally used to allocate the selling price to deliverables in the Company's multiple-element arrangements. The Company determines BESP for deliverables by considering multiple factors including, but not limited to, prices it charges for similar offerings, class of advertiser, size of transaction, seasonality, observed pricing trends, available online inventory, industry pricing strategies, market conditions and competitive landscape. The Company limits the amount of allocable arrangement consideration to amounts that are fixed or determinable and that are not contingent on future performance or future deliverables. The Company periodically reviews its BESP. Changes in assumptions or judgments or changes to the elements in the arrangement could cause a material increase or decrease in the amount of revenue that the Company reports in a particular period.
	The Company recognizes the relative fair value of the media placements or ad services as they are delivered assuming all other revenue recognition criteria are met. Deferred revenue is comprised of contractual billings in excess of recognized revenue and payments received in advance of revenue recognition.
Cost of Sales, Policy [Policy Text Block]	Cost of revenue
	Cost of revenue consists of amounts incurred with digital media property owners that are directly related to a revenue-generating event, direct labor costs, amortization of revenue-producing acquired technologies, Internet access costs and depreciation expense. The Company incurs costs with digital media property owners in the period the advertising impressions are delivered or in limited circumstances, based on minimum guaranteed number of impressions. Such amounts incurred are classified as cost of revenue in the corresponding period in which the revenue is recognized in the consolidated statements of operations.
Advertising Costs, Policy [Policy Text Block]	Advertising expense
	The Company's advertising costs are expensed as incurred. The Company incurred approximately $1.7 million, $1.5 million and $0.6 million in advertising expenses for the years ended December 31, 2014, 2013 and 2012, respectively.
Comprehensive Income, Policy [Policy Text Block]	Comprehensive Income (Loss)
	Comprehensive income (loss) consists of net income (loss) and changes in accumulated other comprehensive income (loss), which are primarily the result of foreign currency translation adjustments and unrealized gains or losses on marketable securities, net of tax.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock-based Compensation
	The Company measures compensation expense for all stock-based payment awards, including stock options granted to employees, directors and non-employees based on the estimated fair values on the date of the grant. The fair value of each stock option granted is estimated using the Black-Scholes option valuation model. Stock-based compensation expense related to restricted stock units (“RSUs”) is based on the grant date fair value of the RSUs. Stock-based compensation is recognized on a straight-line basis over the requisite service period.
	Stock-based compensation expense is recorded net of estimated forfeitures in our consolidated statements of income and as such is recorded for only those share-based awards that we expect to vest. The Company estimates the forfeiture rate based on historical forfeitures of equity awards and adjusts the rate to reflect changes in facts and circumstances, if any. The Company will revise our estimated forfeiture rate if actual forfeitures differ from our initial estimates.
Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]	Goodwill
	Goodwill is not amortized, but is tested for impairment at least annually or as circumstances indicate the value may no longer be recoverable. The Company evaluates goodwill for impairment annually in the fourth quarter of its fiscal year or, whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable. Triggering events that may indicate impairment include, but are not limited to, a significant adverse change in customer demand or business climate that could affect the value of goodwill or a significant decrease in expected cash flows. Through December 31, 2014, no impairment of goodwill has been identified.
	The FASB issued an accounting standard update that permits entities to first assess qualitative factors to determine whether it is more likely than not (a likelihood of more than 50%) that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. This new guidance was adopted by the Company on January 1, 2012 on a prospective basis and the adoption of did not materially impact the Company’s consolidated financial statements. As of December 31, 2014 and 2013, the Company elected to first assess qualitative factors to determine whether it is necessary to perform the two-step annual goodwill impairment test. The Company assessed qualitative factors including its market capitalization, stock price, industry and market conditions, cost factors and cash flows and concluded that it was more likely than not that the fair value of its sole reporting unit is greater than the carrying value of goodwill.
Intangible Assets, Finite-Lived, Policy [Policy Text Block]	Intangible Assets
	Acquired intangible assets consist of acquired customer relationships, developed technology and non-compete agreements. Acquired intangible assets are recorded at fair value, net of accumulated amortization. Intangible assets are amortized on a straight-line basis over their estimated useful lives. The Company reviews identifiable amortizable intangible assets to be held and used for impairment whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. Determination of recoverability is based on the lowest level of identifiable estimated undiscounted cash flows resulting from use of the asset and its eventual disposition. Measurement of any impairment loss is based on the excess of the carrying value of the asset over its fair value. Through December 31, 2014, no impairment of intangibles has been identified.
Stockholders' Equity Note, Redeemable Preferred Stock, Issue, Policy [Policy Text Block]	Preferred Stock Warrant Liability
	Prior to our IPO on August 7, 2013, freestanding warrants related to shares of the Company’s preferred stock that were contingently redeemable were classified as a liability on the Company's consolidated balance sheet. The convertible preferred stock warrants were subject to re-measurement at each balance sheet date up to the date of our IPO and any changes in fair value were recognized as a component of “Other income (expense), net.” As of August 7, 2013, all redeemable convertible preferred stock warrants were converted into warrants to purchase common stock and the liability of $0.4 million was reclassified to additional paid-in capital.
Income Tax, Policy [Policy Text Block]	Income Taxes
	The Company records income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company's consolidated financial statements or income tax returns. In estimating future tax consequences, expected future events other than enactments or changes in the tax law or rates are considered. Valuation allowances are provided when necessary to reduce deferred tax assets to the amount expected to be realized.
	The Company operates in various tax jurisdictions and is subject to audit by various tax authorities. The Company provides for tax contingencies whenever it is deemed probable that a tax asset has been impaired or a tax liability has been incurred for events such as tax claims or changes in tax laws. Tax contingencies are based upon their technical merits, relative tax law, and the specific facts and circumstances as of each reporting period. Changes in facts and circumstances could result in material changes to the amounts recorded for such tax contingencies.
	The Company records uncertain tax positions in accordance with accounting standards on the basis of a two-step process whereby (1) a determination is made as to whether it is more likely than not that the tax positions will be sustained based on the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold the Company recognizes the largest amount of tax benefit that is greater than 50% likely to be realized upon ultimate settlement with the related tax authority.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Issued Accounting Standards
	In February 2013, the FASB issued Accounting Standards Updates (“ASU”) 2013-2, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified out of Accumulated Other Comprehensive Income (ASU 2013-2), to improve the reporting of reclassifications out of accumulated other comprehensive income. ASU 2013-2 requires presentation, either on the face of the financial statements or in the notes, of amounts reclassified out of accumulated other comprehensive income by component and by net income line item. ASU 2013-2 is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2012. The Company adopted ASU 2013-2 in the first quarter of fiscal 2014. The adoption of ASU 2013-2 did not have a significant impact on the Company's consolidated financial statements.
	In July 2013, the FASB issued amended standards that provided explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward or a tax credit carryforward exists. The new guidance provides that a liability related to an unrecognized tax benefit would be presented as a reduction of a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward, if such settlement is required or expected in the event the uncertain tax position is disallowed. The new guidance became effective on January 1, 2014 and should be applied prospectively to unrecognized tax benefits that exist at the effective date with retrospective application permitted. The adoption of these amended standards did not have a significant impact on the Company’s financial position, results of operations, or cash flows.
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which amends the existing accounting standards for revenue recognition. ASU 2014-09 is based on principles that govern the recognition of revenue at an amount to which an entity expects to be entitled when products are transferred to customers. ASU 2014-09 will be effective for the Company beginning in its first quarter of 2017. Early adoption is not permitted. The new revenue standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. The Company has not yet selected a transition method and is currently evaluating the impact of adopting the new revenue standard on its consolidated financial statements.

Upon the closing of the IPO in August 2013, all outstanding warrants to purchase convertible preferred stock converted into warrants to purchase shares of common stock. Consequently, the Company reclassified the balance of these warrants to additional paid-in capital.

[2]

Amounts are presented without giving effect to the Company's 1-for-6 reverse stock split that was effective July 24, 2013, as the number of convertible preferred stock shares did not change.
